Descriptions

**RECHAZADA** NO USAR ESTE NÚMERO DE CANDIDATO. ConsultIDs: ninguna. Motivo: Este candidato estaba en un grupo de CNA que no estaba asignado a ningún problema durante 2017. Notas: ninguna.

USN-4336-1 fixed several vulnerabilities in GNU binutils. This update provides the corresponding update for Ubuntu 16.04 ESM. It was discovered that GNU binutils contained a large number of security issues. If a user or automated system were tricked into processing a specially-crafted file, a remote attacker could cause GNU binutils to crash, resulting in a denial of service, or possibly execute arbitrary code. Various other issues were also addressed.
